Tech Report 1, Part 1: Lighting Proposal Memo TO: Shawn Good FROM: Sarah Miller DATE: 9 September, 2013 SUBJECT: University of Maryland: Prince Frederick Hall This memo discusses the different spaces I will study for the lighting design portion of my senior thesis project. The building I have selected for study is Prince Frederick Hall on University of Maryland s campus. A unique aspect of this building is the programming of spaces it contains. The first floor of this building consists mainly of lecture and classroom space, and the upper floors are dormitory rooms and study spaces. In order to reflect the variety of spaces, my studies will focus on the following: the lobby, the seminar room, a typical dormitory suite, and the entry plaza. The remainder of this memo provides further detail of these four spaces. Lobby The first floor lobby of this building serves as circulation to several key areas of the building: two entry vestibules, a front desk, the resident mail center, elevator lobby, a corridor to academic space, and a corridor to living quarters. 70 34 The most basic function of this space is circulation. Occupants need to navigate through the lobby to reach their intended destination. As such, the lighting should reflect the relative hierarchy of possible destinations for easier wayfinding. To gain a better understanding of each of these spaces, I will first develop three schematic design concepts. Design sketches are a well suited technique to this area because precise light levels are not nearly as important as the contrast and texture created by light. 1

The primary function of this space is for lectures and exams. 44 36 In contrast to the lobby, the overall light level in this space is very important to the function of the room. The primary visual tasks that will take place here are reading and note taking. For this space, I will apply different lighting schemes to accommodate different lecture styles. These will be further developed in later steps to reflect the programming of the space. Possible lighting schemes include one for AV presentations, for professors lectures, and for professors writing notes at the front of the class. note taking reading (printed text as small as 12pt font) reading (computer screen) AV presentations facial acuity of lecturer blackboard/whiteboard visual acuity 2

Of these, there are two main types: single rooms and suites. The dormitory suites offer an opportunity to study a unique special purpose space. Each suite contains two bedrooms, each with two twin beds, for a total of four residents per suite. Suites also have a vestibule area, two bathroom areas, and two closets. I plan to integrate psychological impressions to better reinforce the lighting design in this space. 26 28 Visual tasks that require the most light include reading and writing. However this not simply a study room, this space is the residence of four students, and should be treated as such. Much of the occupant s time will be spent in their room: sleeping, showering, studying, doing homework, watching television, and more. Controllability is very important to the long-term comfort of the occupants. Furthermore the design will have to be flexible enough to accommodate the needs of two people sharing a single bedroom. Furthermore, because half of the typical suites face directly east and the other half faces west, this area also offers the possibility of an integrated architectural and daylighting breadth to better utilize passive lighting. reading, writing, computer based tasks showering, dressing, makeup low light neccessary for sleeping & relaxing 3

This outdoor space serves as a transition space into the lobby. In addition, it offers some seating for campus occupants. 56 136 During the day, when most classes occur, this area will not require any electric lighting. However, this building also contains several floors of dormitory rooms. Students returning to their room at night will needs enough light to feel safe while navigating into the building. Event lighting must also be provided for this space to ensure safety if the building should need to be evacuated at night. wayfinding to building entrance safety & comfort paving: brick paving (PAV-04 & PAV-01) stone dust paving (14/L1.20) conrete paving (01/L1.20) facade: brick (MAS-01) cast stone (MAS-03) metal paneling (PNL-02) curtain wall (PT-02d) 4
